The ZWO ASI120MM-S is a super-fast USB 3.0 version of the ASI120MM lunar and planetary imaging camera.
It can deliver up to 254x frames-per-second at reduced resolution or 60x FPS at full 1280X960 resolution!
Peak QE of 75% (better than the ICX618) and no Fixed-Pattern-Noise!
It is also a very capable guide camera. Compared to ICX618 based cameras, like the Imaging Source DMK21AU618, ZWO ASI120MM offers significantly faster frame-rate, slightly higher sensitivity in visual light and more pixels for lunar imaging.
For guiding it offers a solid performer that handles most setups with ease, including most OAG configurations.
The sensor is protected by an anti-reflection clear optical window. If imaging the Moon or planets we recommend fitting a 1.25" UV/IR rejection filter.
The ASI120MM-S’s mono sensor can also be used with specialised UV or methane band filters, as well as infrared passing filters for lunar and planetary imaging (i.e. Baader IR-Pass, Red and Orange visual filters). IR-passing filters cut short wavelengths which prevents atmospheric dispersion softening the image.
Note: The ASI120MM-S has a Micron sensor which might produce Newton Rings when used with solar telescopes. Cameras fitted with Sony sensors are better-suited to this application.
Supplied with a 150-degree accessory lens so you don't even need a telescope to start imaging the stars!
- The lens can be screwed in too far, result in a scratch on the protect window! Please adjust it very slowly! Don’t turn it beyond the focus at infinity!
